The effect of social interactivity on circle walking depends on the social context. Pigeon circle walking is sensitive to social interactivity and temporal contiguity manipulations in courtship but not in competitive interactions between rivals. The total circle walking duration, average bout duration and total number of bouts are shown for each time delay condition across opposite-sex (courtship) and same-sex (rivalry) interactions. In opposite-sex interactions only, the 9-s delay condition and the Playback condition produced significant effects on circle walking. Error bars indicate standard error. Significant differences between a time delay condition and the Live condition are indicated by asterisks over the time delay data point, *P < 0.05, **P < 0.01, ***P > 0.001.
